Product Overview: Super Duplex UNS S32760 Seamless Tubes
Super Duplex UNS S32760 seamless tubes are high-performance stainless steel tubes made for tough industrial environments. These tubes feature a dual-phase (austenitic-ferritic) microstructure, giving them excellent corrosion resistance and high strength. This creates a balanced structure and improves resistance to harsh chemicals and seawater. Operating between -50°C to 300°C, they are ideal for chemical, marine and petrochemical use. Compared to UNS S32750, S32760 offers slightly better material properties and performance. Super Duplex Alloy S32760 tubes ensure durability, reliability and resistance in extreme conditions.

FAQ
What are the differences between UNS S32750, S32760, and S32950?
What are the differences between UNS S32750, S32760, and S32950?
S32750 is a super duplex steel with strong corrosion resistance and good strength. S32760 has slightly higher chromium, molybdenum, and nitrogen for better acid resistance. S32950 has the highest alloying content, offering maximum pitting and crevice corrosion protection in very aggressive environments.
What is the difference between UNS S32750 and UNS S32760?
What is the difference between UNS S32750 and UNS S32760?
S32760 contains more chromium, molybdenum, and nitrogen than S32750. This gives S32760 slightly better resistance to corrosion and higher strength, making it ideal for more aggressive chemical or marine conditions.
Why are seamless tubes preferred for high-pressure applications?
Why are seamless tubes preferred for high-pressure applications?
Seamless tubes have no weld seam, which means higher pressure resistance and lower leak risk. They are stronger under load and provide smooth flow, making them safer in critical systems.
What is the yield of UNS S32760?
What is the yield of UNS S32760?
UNS S32760 typically has a yield strength of around 550–650 MPa, depending on heat treatment. This high yield makes it reliable in high-pressure and high-stress environments.
What makes UNS S32760 superior to standard duplex stainless steel?
What makes UNS S32760 superior to standard duplex stainless steel?
It has higher chromium, molybdenum, and nitrogen levels, giving better corrosion resistance and strength. It also resists pitting, crevice corrosion, and stress cracking better than standard duplex.
What is a super duplex S32760 equivalent to?
